Abstract
The analysis of the constructed ternary elements and prospects of their development is actual. There are different ways of implementing ternary elements. The problem of development the multivalued logic is the lack of common approach to the implementation of components and elements of non-binary computers. The goal of the work is the comparative analysis the current state of the methods of construction of ternary elements. The history and prospects of development the methods of construction of ternary elements and computer systems on their basis are considered. A comparative analysis of the advantages and disadvantages of such methods of constructing ternary elements as threshold elements of ternary logic based on magnetic elements, ternary elements based on λ-transistor, CMOS transistor and CMOS-C transistors, on binary logic, mathematical models of ternary elements based on neurons, threshold element on bipolar transistors and multithreshold element of multivalued logic according to the main criteria, such as: speed, power consumption, complexity of the structure, the possibility of integrated implementation was made. The future directions of work and expediency of development of subjects of construction of ternary elements and systems on their basis are outlined. All the considered methods of implementation of ternary elements have a number of significant disadvantages. Only using the multithreshold element of multivalued logic allows to create the ternary elements with general approach. One of the obstacles hindering the development of ternary technology is the lack of element base and a common approach to the implementation of components and elements of non-binary computers. Implementing ternary devices based on threshold logic is a way to create ternary devices that can compete with binary devices in terms of equipment.
